GEORGE F. BLACK, OF BALTIMORE, MARYLAND,

COMBINED SASH HOLDER AND FASTENER.

To all 'whom t may concern.'

Be it known that l, GEORGE F. BLACK, a citizen of the United States,residing at Baltimore, inthe State of Maryland, have invented certainnew and useful Improvements in Combined Slash Holders. and Fasteners;and l do declare, the following to be a full, clear and exactdescription of the invention, such as will enable others skilled in theart to which it appertains, to make and use the same.

This invention relates to a combined sash holder and fastener.

The object of the invention is to provide a novel device of thischaracter which is of such construction that it will hold the windowopen when itis one position, and when reversed to another position, willre tain the window in locked position, that is when the window isclosed.

Another object of the invention is to generally improve upon devices oithis class by providing one oi' extreme simplicity, one which is highlyeilective in operation, one which is easy to manipulate, one which willnot inar or bruise the woodwork as the majority of devices of this classdo7 and one which is extremely inexpensive to both the manufacturer anduser.

Other objects and advantages of the in vention will be apparent duringthe course Vof the following description.

In the accompanying drawings forming apart of this specification and inwhich like numerals are employed to designate like parts throughout thesame:

Figure l is an elevational view of a device constructed in accordancewith my invention, showing the same applied and disclosing the positionit takes when it is ineffective.

Fig. 2 is a view showing the position the device assumes when holding awindow in the window in closed position.

Fig. 3 is a view showing the device reversed, which position it assumesto retain the window in closed position.

Fig. l is sectional view taken on the y line 4-4 of Fig. 3, looking inthe direction Fig. 2.

Specification of Letters Patent.

F ig. 6 is a detail perspective view 'of a device constructed inaccordance with my invention disclosing one method of making the same.

Fig. 7 is a like view showing another method of making the device. v

In the drawings for the purpose of illustration, I have shown a portionof a window frame, designated bythe numeral l, and portion of a windowwhich slides in the trame, being designated by the numeral `2. M yimproved device is to be applied on the window in such a position as toengage the window frame.

rlhe device comprises a fiat metal triangular plate 3 provided with acentrally disposed slot 4l which extends from a point adjacent the baseof the triangle, to a point adjacent the apex thereof. In addition tothis slot, the plate is further 'provided' with a plurality of ears 5,two of which are at the corners of the plate, and the other ol which isat the apex of the plate. Each of these ears'projects outwardly beyondthe two converging edges of the plate, andthe edge of each ear isrounded in the manner shown.

Carried by the two ears adjacent the base of the plate, are cylindricallugs 6 which serve a purpose to be described and also serve as knobs orhandles, as will be hereinafter more thoroughly set forth. Carried bythe remaining ear is another lug `7 .of arcuate formation. These lugsinconjunction with the ears form a plurality oi' friction shoes which arespaced from one another andare designed to engage the window frame l inthe manner shown. By this arrangement it is possible to reverse theplate to either of the positions shown in Figs. 2 and 3, and in eitherof these positions a two-point contact will be had. is to be laid onthis two-point contact feature because of the fact that it insureseffective operation of the device. To describe this Vfeature morethoroughly it may be said that because of this construction theVfriction shoes will obtain an effective grip von the window frameregardless of whether or not there are slight irregularities on theframe. It may be stated` that on some window frames there may` beprojections in Patenteiimv. 9,1920; Application filed May 13, 1920.Serial No. 381,140. l

the form of hardened paint, tacks, and the like, and if the edges of theplate were corrugated orsmooth, an effective grip would not loe had dueto the fact that the edge of the plate would not engage suchirregularities but would merelyslipV over them' and not take hold. W ithmy construction this is not thelrcase, because the,

friction shoes extend outwardly from the divergent edges of the plate,consequently the shoes will at all timesobtain an effective grip-whether or not there Aare irregularities on the window frame. This' isa, feature of construction to be carefully considered. Close examinationof the disclosure of the devicecwill disclose'the fact that the' curvedworking surfaces of the lugs 6 and ears 5 are flush with one another..By working surfaces I meanthesurface of these parts which frictionally'engage the window frame. Due to Vthis manner of constructing thefriction shoes, it will be seen that the shoes cannot mar or bruise thewoodwork'as the majority of devices of this class do. This is anotherfeature of vconstruction to be carefullyconsidered. rThe 'lugs 6 inaddition to forming a part ofthe friction shoes, serve as knobs orhandles, kby'means ofwhich the plate is reversed from the position shownin Fig. 2 to the position shown in Fig., 3. v

In thel construction of inv device so far described, it will be' seenthat the plate 3, ears 5, and the lugs 6 and -7 are made of a singlecasting. This isone way of making the device, but I do `not desire` tolimit myself to this method of construction, be

cause it may be made in the manner shown in Fig. 7.v By referring tothis figure it will be seen that the device is stampedfrom sheet metal.For the sake of convenience and clearness of description, I will placethe same reference characters on this form of my invention as areemployed to designate the several parts of the forni of Vmy inventionshown in Fig. 6. n

' In use, the plate 3 is fastened upon the window frame 2 by means of ascrew or the like 8, the latter extending through the slot 4'in theplate. In its normal position, the device will take the position showninFig. 1, wherein the screw 8 is at one end of the slot 4. It is forthis reason that I form the lug Tof arcuate formation. To explain, it isto be said that by-so forming the lug, a clearance space for the headofthe-screw 8 will be had. If it is desired to hold the wini dow in anelevated position, one of the'friction shoes, which serve as handles,may be gripped and the plate krnoved to the position, shown in Fig. 2.This may be done by merely pushing the plate upwardly from the positionshown in Fig. l. l Vhen in this position the slot 4 is inclined towardthe window frame, and vshould the window move action will be obtained,it may be necessary to hold the vdevice Vagainst movement with one handwhile the window is moved slightly downwardwith the other hand.Thispractice will prevent the` device from dropping,

due to its weight,-to an ineffective position,

as it might do ify it were not held in the foregoing manner. ToV retainthe window in locked position when it is closedfit is obvious that it isonly necessary to reverse the position of the device from that justdescribed to the position shown in'F ig. 3, Y

wherein the base of the triangular Vplate is swung upwardly. When inthis position the slot'4 will-be inclined at a different* angle,consequentlyif an attempt'is made to raise the window, the Vscrew actingin the slot will force the friction shoes into effective engagement withthe window frame and prevent the window from being opened.

A device constructed in accordance with my invention will be foundextremely novel and advantageous, due to the fact that the frictionshoes will always obtain an effective grip on the window frameregardlessof whether or not the latter has any irregularities thereon.It may be stated at this point, that in many cases there is a weatherstrip secured on the window frame, consequently there is a slight space,in some cases, between the weather strip and the window. Because ofthis, it is necessary that the plate be ofsuilicient thickness toprevent it from working into this space and not obtaining a grip. WithVmy construction I overcome any such circumstances because the lugs 6 and7 project far enough beyond the'pl'ate to 'prevent this. My device isextremely simple and easy to manipulate, andis inexpensive.

I am aware that devices of similar construction to mine are patented andare in use, but I do not know of any device that possesses all theconstructional Vadvantages that my device does. u

A oarefulconsideration of the foregoing description will enable personsskilled in the art to which this invention relates, to obtain athorough'understanding of the same, therefore, further description isdeemed unnecessary.

I claim:
